Abstract

The temperature dependence of the infrared absorption spectrum of ZnSe was measured by using a variable temperature, liquid nitrogen cooled, absorption cell interfaced with a Fourier transform infrared spectrometer. Absorption difference spectra were obtained as a function of temperature by using the on-board computing facilities of the spectrometer coupled with its data storage capabilities. The temperature dependence of the absorption feature, which extends from about 450 to 800 cm⁻¹, is shown to be consistent with a two phonon interaction as have been previously suggested.
